Long Island Viaduct
Bridge connecting Long Island to Moon Island, which in turn is connected to the mainland by a causeway. Mainly used to access a large shelter for the homeless. Closed in October 2014 after years of neglect caused the bridge to be on the brink of failure. Scheduled for replacement over the next three years.
